WATER HEATER AND FILTER.

Application filed July 29, 1915, Serial No. 42,636.

To all whom it may concern:

Be it known that We, CHARLES JOERIN, Jr.,. and ALBERT E. JonRIN, citizens of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Water Heaters and Filters, of which the following is a speci fication, reference being had therein to the accompanying drawings.

This invention relates to a filter adapted to supply either hot or cold Water and to an arrangement of parts that makes the device particularly available and suitable for use in a doctors or dentists operating room, at a counter where hot or cold drinks are served, and in other places where it is desired that the apparatus be instantly ready for use but of compact and ornamental form.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claim.

Referring to the drawings,

Figure 1 is a view in elevation of a filter that embodies features of the invention;

Fig. 2 is a plan view thereof, and

Fig. 3 is a view-in section taken on or about line III-III of Fig. 2.

Referring to the drawings, an outer cylindrical casing 1 of suitable material has a cap 2 properly secured thereto and arranged to support a filter cylinder 3 that is secured against the underside of the cap by a suitable clamping rod 4 and holding member 5. An impervious washer 6 is interposed between the nut 5 and the end of the sleeve While a suitable packing ring 7 prevents leakage around the joint between it and the cap. The cylinder is of suitable porous material and permits the passage of water therethrough from a main inlet 8 in the base of the casing 1 to a main outlet 9 in the cap. Preferably thumb screws 10 that engage through the cap into lugs 11 form the means by which the cap is secured in place on the casing and admit of its ready removal for washing out of the filter.

A main duct 12 in the cap leads from the main inlet 9 is one direction to a cold water faucet 13 that is mounted on the cap so as to be conveniently manipulated. The passage also discharges into a suitable fitting 14: with double discharge openings, one of the latter being in communication with an outer helix or coil 15 of copper tubing and Specification of-Letters Ia'tent.

the ,other with an inner helix of less diameter, as indicated at 16, likewise of copper tubing-or other suitableheat conducting material. The discharge ends of both helices are connected to a hot water faucet 17.

A suitable jacket 18 with bonnet 19 and lining 20 of insulating material envelops the coils and detachably engages over the cap 2. A gas supply pipe 21 discharges through a regulating cock 22 into a suitable burner 23 of the air mixing type that passes through a suitable opening of the casing and through a flange 24 on a cap over which the casing or jacket 20 telescopes, and underneath a foraminous shield or mixing plate 25 that rests on the flange beneath the coils. WVhen ignited the flame or the heat therefrom practically envelops both coils, the products of combustion escaping through the bonnet 19.

A link 26 articulates the handle or operating lever 27 of the gas cock 22 and the handle 28 by which the hot water faucet 17 is operated. When the handle 28 is swung,

' the gas is discharged through the burner 23 which is supplied with a pilot tube 29, and a pilot light from the jet end of this tube ignites the gas and indrawn air in the burner 23 whenever the water passage is open.

Because of this disposition of parts, a filter is obtained that is compact, of pleasing design, and of high efliciency. The supply of water under pressure is properly filtered and is discharged under head from either the hot or cold Water faucets. When the hot water faucet is open, the distribution of heat through the long coils which the water is forced to travel heats the contents of the latter and cause a quick delivery of the desired amount at the faucet.

Obviously, changes in the details of construction may be made without departing from the spirit of our invention and we do not care to limit ourselves to any particular form or arrangement of parts.

What we claim is A water filter and heater comprising an upright casing with heating coils therein, a water filter cylinder disposed below and in axial alinement with the coils and provided with an enveloping casing, a ca comprising a division wall between the filter and coils and containing water outlet connections from the filter to the coils, a

gas burner extending into the coil casing der and the chamber formed by the coil on the cap, and a water outlet connection casing. 1 r
